Straw of Trouble

thingiverse

I attempted to build a Tesla valve but botched it, resulting in a 2-way active valve instead. Now my creation is essentially a straw that obstructs airflow when trying to blow through both ends at once. Thankfully, since this isn't designed for high-pressure, short-duration applications, the issue isn't extremely noticeable. To fix this, I recommend applying a food-safe coating to seal the minuscule gaps between layers, preventing small holes from forming. If you want to use your creation as an actual drinking straw, consider using food-safe art resin instead.
